(Phys.org)—Russian astronomers have recently observed a giant radio flare from a strong X-ray binary source known as Cygnus X-3 (Cyg X-3 for short). The flare occurred after more than five years of quiescence of this source. ...

The living machinery responsible for photosynthesis - while commonplace and essential to life on Earth - is still not fully understood. One of its molecular mysteries involves how a protein complex, photosystem II, harvests ...

(Phys.org)—A new accreting millisecond X-ray pulsar (AMXP) has been found in one of our galaxy's most massive clusters, NGC 2808. The newly detected AMXP received designation MAXI J0911-655 and is part of an ultra-compact ...

Scientists have used the powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory to make the first snapshots of a chemical interaction between two biomolecules - one that flips an RNA "switch" ...

Astronomers have used NASA's Chandra X-ray Observatory and other telescopes to show that a recently-discovered galaxy is undergoing an extraordinary boom of stellar construction. The galaxy is 12.7 billion light years from ...

Galaxy clusters contain a few to thousands of galaxies and are the largest bound structures in the universe. Most galaxies are members of a cluster. Our Milky Way, for example, is a member of the "Local Group," a set of about ...

With the help of experimental studies on molecular level, researchers are acquiring increased knowledge on how plants form oxygen from water molecules. An international research team has now found a way to visualise this ...

A snapshot of the stellar life cycle has been captured in a new portrait from NASA's Chandra X-ray Observatory and the Smithsonian's Submillimeter Array (SMA). A cloud that is giving birth to stars has been observed to reflect ...

Astronomers may have solved the mystery of the peculiar volatile behavior of a supermassive black hole at the center of a galaxy. Combined data from NASA's Chandra X-ray Observatory and other observatories suggest that the ...

In 1986, Gordon Brown used SLAC's Stanford Synchrotron Radiation Lightsource (SSRL) to visualize something no one had ever seen before: the exact way that atoms bond to a solid surface. The work stemmed from a eureka moment ...
